The jig 1 is formed of an elastic body such as rubber or resin, with the basic portion 2, the first protruding portion 3, and the second protruding portion 4 being integrated.

  The backbone 2 is formed in a plate shape. The backbone part 2 of the present embodiment is formed in a disc shape. The trunk portion 2 functions as a stopper portion that restricts the movement of the elevator landing door 50 in a state where the jig 1 is provided in the sill groove 51 (see FIG. 3). As for the basic | foundation part 2, the 1st protrusion part 3 and the 2nd protrusion part 4 are each formed in protrusion part formation surface 2a, 2b which mutually opposes in parallel. The backbone portion 2 also functions as a transmission portion that transmits a force for press-fitting the first projecting portion 3 or the second projecting portion 4 into the sill groove 51. The trunk portion 2 is in a state in which the jig 1 is provided in the sill groove 51 (see FIGS. 2 and 3), and one of the projecting portion forming surface 2a and the projecting portion forming surface 2b is the upper surface in the vertical direction, and the other is It becomes the lower surface in the vertical direction.

  The first projecting portion 3 projects from one projecting portion forming surface 2 a of the trunk portion 2. The second projecting portion 4 projects from the other projecting portion forming surface 2 b of the backbone portion 2. The 1st protrusion part 3 and the 2nd protrusion part 4 of this embodiment are formed in rectangular plate shape. At least one of the first protrusion 3 or the second protrusion 4 can be press-fitted into the sill groove 51 of the elevator landing door 50. Both the 1st protrusion part 3 and the 2nd protrusion part 4 of this embodiment are formed in the dimension which can be press-fit in the threshold groove 51. FIG. The 1st protrusion part 3 and the 2nd protrusion part 4 function as a holding | maintenance part hold | maintained at the threshold groove 51 in the state press-fitted and fitted to the threshold groove 51 (refer FIG. 2, FIG. 3).

  Here, the first protrusion 3 and the second protrusion 4 are formed so that the protrusion dimensions H1 and H2 in the protrusion direction, the width dimensions W1 and W2 in the width direction, and the thickness dimensions T1 and T2 in the thickness direction are substantially equal. . Moreover, the 1st protrusion part 3 and the 2nd protrusion part 4 which are formed in plate shape are formed so that both surface directions may become parallel. That is, the first projecting portion 3 and the second projecting portion 4 are formed in a dimensional relationship and a positional relationship that are substantially plane-symmetric with respect to the trunk portion 2.

  In addition, the said protrusion direction is the 1st protrusion part 3 and the 2nd protrusion part 4, and the 1st protrusion part 3 and the 2nd protrusion part 4 protrude with respect to the protrusion part formation surfaces 2a and 2b of the basic | foundation part 2, respectively. The direction is typically a direction orthogonal to the protrusion forming surfaces 2a and 2b. The width direction is a direction orthogonal to the projecting direction in each of the first projecting portion 3 and the second projecting portion 4. Typically, the first projecting portion 3 and the second projecting portion 4 are formed in the sill groove 51. It is a direction along the extending direction of the sill groove 51 in the press-fitted state (see FIGS. 2 and 3). The thickness direction is a direction orthogonal to the protruding direction and the width direction in each of the first protruding portion 3 and the second protruding portion 4, and is typically the first protruding portion 3 and the second protruding portion 4. Is a direction orthogonal to the extending direction of the sill groove 51 in a state where the sill groove 51 is press-fitted into the sill groove 51 (see FIGS. 2 and 3). Here, since the 1st protrusion part 3 and the 2nd protrusion part 4 are formed in the plane symmetrical form on the basis of the trunk | skeleton 2, the protrusion direction of the 1st protrusion part 3 and the protrusion of the 2nd protrusion part 4 are formed. The direction, the width direction of the first protrusion 3 and the width direction of the second protrusion 4, and the thickness direction of the first protrusion 3 and the thickness direction of the second protrusion 4 all coincide.

  Moreover, the 1st protrusion part 3 and the 2nd protrusion part 4 are each extended and formed from one edge of protrusion part formation surface 2a, 2b with respect to the width direction. Moreover, the 1st protrusion part 3 and the 2nd protrusion part 4 are formed so that protrusion dimension H1, H2 may become shorter than the depth dimension D (refer FIG. 2) of the sill groove 51. FIG. The first protrusion 3 and the second protrusion 4 are in a state where the first protrusion 3 and the second protrusion 4 are press-fitted into the sill groove 51 (see FIGS. 2 and 3). In each of the second projecting portions 4, the opposing surfaces 3 a and 4 a that oppose each other in the thickness direction become contact surfaces that contact the groove side surface 51 a of the sill groove 51. Note that the configuration in which the surface directions of the first protrusion 3 and the second protrusion 4 are parallel as described above typically means that each of the opposing surfaces 3a of the first protrusion 3 and the second protrusions. This corresponds to a configuration in which the four opposing surfaces 4a are parallel to each other.

  The jig 1 configured as described above is assembled in the sill groove 51 after an elevator landing door 50 is opened by an operator, for example, during elevator installation work or maintenance inspection work. For example, the worker holds one of the first projecting portion 3 and the second projecting portion 4 of the jig 1 with a finger and holds the other one of the first projecting portion 3 and the second projecting portion 4. Press fit into the groove 51. In the example of FIG. 2, the jig 1 has a second positional relationship in which the first protrusion 3 is gripped by an operator and the width direction of the second protrusion 4 is along the extending direction of the sill groove 51. The protrusion 4 is inserted and pushed into the threshold groove 51. Thereby, as for the jig | tool 1, the said 2nd protrusion part 4 is press-fit by the threshold groove 51. As shown in FIG.

  At this time, the operator presses the finger 2 against the backbone 2 of the jig 1 (see the arrow in FIG. 2), thereby pressing the second projecting portion 4 into the sill groove 51. It can be efficiently transmitted to the second protrusion 4. In other words, the jig 1 can transmit the pressing force directly to the second projecting portion 4 through the trunk portion 2, with the trunk portion 2 functioning as a transmission portion.

  The jig 1 is formed such that the projecting dimensions H1 and H2 of the first projecting portion 3 and the second projecting portion 4 are shorter than the depth dimension D of the sill groove 51. For this reason, the jig 1 can press-fit the second projecting portion 4 into the sill groove 51 until the bottom surface of the trunk portion 2, here, the projecting portion forming surface 2 b contacts the landing sill 52.

  As shown in FIG. 3, the jig 1 has the end surface of the trunk portion 2 and the lower end portion of the end surface 50 a of the elevator landing door 50 in a state where the second protrusion 4 is press-fitted into the sill groove 51. It functions as a stopper part by contacting. Thereby, the jig | tool 1 can regulate the movement along the sill groove 51 of the elevator hall 50. At this time, the jig 1 serves as a holding portion by a frictional force generated between each opposing surface (contact surface) 4a of the second projecting portion 4 press-fitted into the sill groove 51 and the groove side surface 51a of the sill groove 51. The second projecting portion 4 functions and is held in a state where the second projecting portion 4 is press-fitted into the threshold groove 51. As a result, the jig 1 can be temporarily fixed and held with the elevator hall 50 opened. Further, as described above, the jig 1 has the bottom surface of the trunk portion 2, in this case, the projecting portion forming surface 2 b firmly with the landing sill 52 in a state where the second projecting portion 4 is press-fitted into the sill groove 51. Therefore, a sufficient contact area between the trunk 2 and the landing threshold 52 can be ensured. As a result, the jig 1 can be configured such that the second projecting portion 4 is not easily removed from the sill groove 51, and can be temporarily fixed and held in a state where the elevator landing door 50 is opened more reliably.

  In the above description, the jig 1 has been described as having the first protrusion 3 gripped by the operator and the second protrusion 4 being press-fitted into the sill groove 51. Good. In other words, the jig 1 may be such that the second protrusion 4 is gripped by an operator and the first protrusion 3 is press-fitted into the sill groove 51.

  Then, for example, after the operator completes the predetermined work in the hoistway or the like, one of the first projecting portion 3 and the second projecting portion 4 of the jig 1, the first projecting portion 3 in the example of FIG. 3. The jig 1 can be removed from the sill groove 51 by grasping with a finger and pulling out the second protrusion 4 from the sill groove 51. Thereby, the jig | tool 1 can return the elevator hall 50 to the state which can be opened and closed again.

  Therefore, the jig 1 of the present embodiment can be temporarily fixed and held with the elevator landing door 50 opened in a simple operation as described above, so that workability can be improved. For example, since the jig 1 is configured as a single part in which the respective parts are integrated, the elevator landing door is formed by press-fitting the first projecting portion 3 or the second projecting portion 4 into the sill groove 51. Since 50 can be held in the door open state, workability can be improved. Moreover, since the jig | tool 1 can prevent the operation | work which loosely tightens a screw | thread etc., for example at the time of use, it can improve workability | operativity also in this point.

  Furthermore, since the jig 1 is composed of a single part as compared with a case where it is composed of a large number of articles, for example, the jig 1 is not easily broken, and can be used when one of the constituent articles is defective or lost. It is possible to prevent the situation of disappearing. Moreover, since the jig | tool 1 can mainly determine the exchange | requirement reference | standard since the site | part which can deteriorate over time is mainly the 1st protrusion part 3 and the 2nd protrusion part 4, safety | security is improved as a result. You can also.

  Moreover, since the jig | tool 1 is comprised with an elastic body, even if it falls within a hoistway, since damage to an apparatus, damage to a customer's design thing, etc. can be suppressed, also in this point Workability can be improved. Moreover, since the jig | tool 1 is comprised with an elastic body, even when it is a case where it contacts with customer design objects etc. at the time of carrying etc., the damage etc. of the said customer design articles etc. can be suppressed.

  Furthermore, since the jig 1 can efficiently transmit the pressing force to the second protruding portion 4 via the trunk portion 2 when the operator press-fits the second protruding portion 4 into the sill groove 51, The loss of force during insertion can be reduced, and workability can also be improved in this respect.

  In the above description, the first projecting portion 3 and the second projecting portion 4 have been described as being press-fit fitable in the sill groove 51, but at least one of them may have a shape and size capable of press-fit fit. That's fine.

  According to the jig 1 described above, the backbone 2, the first protrusion 3, and the second protrusion 4 are provided. The backbone 2 is formed in a plate shape. The first projecting portion 3 projects from one projecting portion forming surface 2 a of the trunk portion 2. The second projecting portion 4 projects from the other projecting portion forming surface 2 b of the backbone portion 2. And at least the 1st protrusion part 3 or the 2nd protrusion part 4 can be press-fitted and fitted to the sill groove 51 of the elevator hall 50. Therefore, since the jig 1 can be temporarily fixed with the elevator hall 50 opened by a simple operation, workability can be improved.
